Re: [Paraview] Using 64 or more cores on a single node when running client/server
If you're running on the DSRCs I'm guessing that the limit is coming from the node selection option (i.e. "#PBS -l select=8:ncpus=36:mpiprocs=8"). mpiprocs here is the number of MPI processes per node while ncpus is the number of cores per node (in this case only nodes that have 36 cores per node will be used. I've never tried having mpiprocs higher than ncpus. I would guess that a simple MPI helloworld would really show whether or not this is where the limit is coming from.

There's nothing in ParaView that checks how many cores your node has, as a result if there's a cap, it's coming from the MPI implementation itself. ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
Re: [Paraview] Using 64 or more cores on a single node when running client/server
Yes, it works. Paraview 5.4 with OpenMPI 1.7.3 konsole─┬─bash───mpirun───80*[pvserver] ├─bash └─{konsole} Node: 20 cores with hyperthreading. It should be related to your mpi environment: may be oversubscribing (more than one mpi process by core) is not the default behavior.
